This case relates to weighing scales and auxiliary devices controlled thereby.` h

Generally, the object of the invention is to provide novel means for controlling aux- 5 iliary devicesfrom a scale. U

Further, the object is to control 4,auxiliary devices from a Eescale without interfering with the freedonr of movement of any part of' the scale.

Further still, the object is tol sense or analyze the position of the scale under aload.

by means which do not contact with the scale at any time and to control by the sensing or analyzing means an indicating or registering or recording means.

Another object is to differentially control a counter or recorder by a lyzer. Still another object is to analyze multidenomination loads on a scale with a minimum of error by confining each selection by the analyzer to a definite load.

Another object is tosuccesslvely analyze different denominations of a load on a scale.

Fig. 21 is a section similar to Fig. l of a. modified analyzer.

rIhe invention is herein illustrated and described in connection with a five hundred pound scale of the pendulum dial type Shown in Patent 1,777,873. It will be obvious that the principles of the invention are applicable equally well to many other types of scales. .n

In detail, referring to Figs. l to 3 which show the structure of the scale and selector parts, 1() is the supporting frame for pendulums l1 and indicator shaft 12 which carries a pinion`13 driven from the pendulum systeml as more fully shown in above mentioned Patent 1,777,873.

At its right end, as viewed in Fig. 1, the indicator shaft carries a pointer 14 movable over the face of an indicating scale dial 15 in thel form of a ring graduated in pounds from 0 to 500. 1n back of the scale dial, frame 10 supports a circular bracket 2() to which is attached by bolts 21 a selector or load analyzer assembly. The latter includes i nermost bands represent 2l E Y 1,914,388

der 400, 300, 200, and 100 pound readings. The next nine bands respectively representl in descending radial order, 10, 20, 30, 40,

90 poundreadings, while the inin descending radialorder1,2,3.....9.l

Sec'ured to the face of the disk 23 and covering the bands 24 is an insulator plate 25 of mica or the like perforated in accordance with the dial indications.' The perorations 26 in combination with bands 24 translate the dial indications.

Thus, as shown in Figs. 2 and 3, the indication 498 on the dial is translated by a perforation 26a in mica plate 25 in front of the 400 pound band 24, aperforation 2Gb in front of the 90 pound band 24, and a perforation 26o in front of the 8 pound band 24. f Secured to the assembly in front of and -substantially in contact with mica plate i face of: insulator disk 27.

jg ring 29 located inside the dial ring. The

is an insulator disk er ring 27 in which are set `five hundred r'adial conductive barsl 28. The latter are circumferentially Vspaced apart and one bar is provided'for each 'pound position on the scale diall5.' i

' The scale dial 15 is secured to the front y Also secured to the :front face of the disk 27 is a conductive inner circumferential Aedge of ring 29 terminates substanially at the sameradlal distance from the axis of rotationv of pointer i strip-32.

15 as the inner edges of radial bars 28. The pointer 14 carries a small light bracket 30 to which is fastened an insulator block 31 carrying an axially extending conductive The strip 32 extends across the inner edges of radial bars 28 and conductive ring 29 and is the saine radial distance from both. After the radial bars and the conductive ring 29, have vbeen fixed inv the assembly, their inner edges may be accurately finished to form true circles concentric with the path of the strip 32. A

There is a gap between the strip 32 and the adjacent radial bar 28 `and a similar gap between the strip 32 and the lnner` edge of ring 29. By disposing strip 32 parallel to shaft 12 of the indicator, endwise movement of the latter does not vary the length of the gaps.l When the pointer comes to rest under a load, the strip 32 thereon is adjacent a radial-bar 28 corresponding to the load.

According to this invention, a circuit is formed between ring 29, strip 32, and the adjacent bar 28 in which the gap between the strip and bar 28 and that `between the strip and ring 29 are bridged by sparks.

One method of forming this circuit is shown in Fig. 5. Referring to this figure, the current flows from one side of a battery 34 through a hand switch 35, the primary winding 37 of an induction coil, and

through an interrupter 36 to the other side of the battery. Interrupter 36 functions to intermittently interru t ener 'zation of winding 37, thereby in ucing a. igh tension charge in the secondary windin 38. From one `side of the secondary the e arge is led through a line 39 to the conductive ring 29 from which a spark discharges to strip 32 from which in turn a s ark jumps to that radial bar 28 closest to t e strip. yFrom the bar 28, sparks are discharged through the perforations 26 covered by this bar to the bands or hoops 24 behind these perforations. The maximum reading in the instant case is a three denomination number. Assume for example that the load is 498 pounds.v Referring to Fi 3, the radial bar corresponding to t is loa covers a. perforation 26a in front of the outermost or 400 lb. hoop 24, a perforation 261) in front of the 1b., hoop 24, and a perforation 26e in front of the 8 lb. unit, hoop 24. Sparks may jump successively in any order or simu taneously as the case may be from the radial bar through perforations 26a, b, and c and to the 400 lb., 90 lb., and 8 1b. hoops 24. To each hoop is connected a terminal plug 40'from which a line 41 goes to one side of a high tension magnet 42.

The other side of the magnet is in series with normally closed contacts 43 and 44. From a. contact 44, a lead 45 returns to the secondary 38 of the induction coil, in the above manner, circuits are formed through high tension magnets 42 corresponding to the load on the scale. Upon energization of a magnet 42, its amature 47 is attracted releasing contact 43 carried thereby from divided contacts 44 and opening the circuit through magnet 42. While releasing contact 43 from contacts 44, the armature closes contacts 48. This energizes a low tension magnet 49 in series with a recorder control magnet 50 and a battery 51. rMagnet 49 holds armature 47 attracted to prevent c0ntacts 43 and 44 again closing. Magnet 50 sets means for controlling the recorder device which will be further explained hereinafter.

Fig. 6 is a circuit diagram of a different arrangement for forming the high tension circuits. In this arrangement, three induction coils are used, primaries 61 being connected at one side to a common line 62 leading to hand switch 63 and the plus side of a battery 64. The other sides of the primaries are connected through their interrupters 65 to separate lines 66 which lead to contacts 67 engageable with contacts 68 on pivoted armature blades 69 of relay coils 70. There is one coil 70 in series 1n the same circuit with one of the recorder magnets 50 and connected low tension magnet 49. The armatures are connected through a common line 71 to a contact blade 72 having a contact stud 7 3 engageable with a through lead 79 is connected to the minus.

side of the battery 64.

The contacts 76 are controlled by a solel noid 80, the core 81 of which has at its upper end a pin 82 for engaging the upper Contact blade 75. The circuit through solenoild is adapted to be completed through the contact strip 83 having opposite contact lugs 84 centrally disposed between contact lugs 8 5. lever 86 pivoted to the plunger rod 87 of a plunger 88 movable in an auxiliary dash pot 89. The latter .through pipes 90 is connected to the main' dash pot 91, the piston 93 of which is connected to a movable element 94 of the weighing scale. Then a load is placed on the scale, the liquid in the dash pots 91 and 89 is caused to surge. This surge continues at a decelerating rate until element 94 comes to rest. At this time. the scale is in equilibrium under the applied load. Thile the liquid in the dash pot is surging. the bell lever 86, oscillates correspondingly oscillating spring strip 83 and lansing rapid making and breaking of contacts 84 and 85. The

'contacts are made rapidly enough to cause a circuit to be formed through solenoid 80 from the plus side of the battery 64 through switch 63, line 95, the `solenoid 80, line 96, strip 83, contacts 84, 85 and line 97 to the minus side of the power source. noid being energized moves the core. 81 upwardly releasing contact blade 75 and causing contacts 76 to break. While iontacts 76 are open, the circuit through the primaries cannot be con'lpleted. When the Scale is in equilibrium` contacts 84 and 85'are open, solenoid 80 is deenergizcd and core 81 descends engaging contact blade 75 to close contacts 76. N ow if control button 98 is depressed, it will more contact blade 74- three perforations, one in each denomination of a three denominational order load to the hoops 24 behind the pcrforations. The hoops 24 are. connected to high tension magnets 42 which when energized operate The strip 83 is carried by a bell The solepivoted armatures 47 to close contacts 48.

'These contacts vclose a circuit from plus side of battery 64, through hand switch 63, lines 95 and 62, contacts 48', low tension magnets 49', recorder magnets 50, primary control magnets 70, blade 72, contacts 73 (now closed by key 98), blades 74 and 75,v contacts 76,

blade 78 and lines 79 and 97 to the minus kside of the battery.

Assume that instead ot sparks jumping simultaneously from the radial bar 28 through the three perfor-ations, a spark Afirst discharges from the radial bar 28 associated with the hundreds bank.

Energization of this relay 70 attracts its armature 69 breaking contacts 67 and 68. The circuit through the primary of the connected induction coil is thus broken, breaking the circuit through the secondary thercoi` and thus deenergizing the magnet 42 controlled thereby. Ilnergization of serially connected magnets 49', 50, and 70 is maintained, however, until contacts 7 3 are opened as will be hereinafter explained. The hundreds induction coil is now inoperative and either the tens or units induction coil is next operative to energize the associated magnets 42', 49', 50, and 70 of a recorder bank.

In this manner, the recorder magnets 50 may be successively energized without employing a high tension spark gap such as between contact-s 44 of the first form (Fig. 5) to interrupt the circuit through the high tension magnets.

Fig. 7 is a circuit diagram of still another form of the invention. In this form, the order in which the spark gaps of the hundreds, tens, and units bank are bridged is predetermined. Here again as in the first form, a single induction coil is used. The primary 100 ot the induction coil is connected by line 101 to the minus sideof the storage batt-ery B. The other side of the .primary is connected through interrupter 102 and line 103 to a contact blade 104 having a contact 105 engageable with contact 105 on a blade 106. The latter through line 107 and main switch 108 is connected to the plus side of the battery. Contacts 105 make under control of a rotary ratchet cam 109 having three similar spiral teeth 110. As the cam 109 makes one revolution. the teeth 110 will cause the contacts 105 to make three times. Each tooth is shaped to hold the contacts closed an appreciable time.

Between successive teeth 110, there is an abrupt drop so that the contacts 105 will be rapidly broken when the blade 101 dro )s ott' the high point of a. tooth. While the contacts 105 are closed by a tooth 110, interrupter 102 causes surges in the E. M. F. of the primary coil which induces a high E. M. F. in the secondary coil 111. As in the previous forms, one side of the secondary is connected to the common conductive ring 29. In the present form, the other side of the secondary is connected by lead 112 to a brush 113 engaging contact ring 114 of a distributor. The contact ring has a laterally extending contact segment 115-which as it rotates in the direction of the arrow successively engages a units brush 116, a tens brush 117, and a hundreds brush 118. The units brush 116 is connected by lead 119 to one side of each high tension magnet 42k of the units bank. These magnets are similar to the magnets 4 `bf the second form of the invention. The other sides of unit magnets 42 are connected to their respective unit bands 24. While the contact segment 115 is engaged by units brush 116, the tendency for the charge on the i-radial bar 28 corresponding to the applied load is to discharge through the unit perforation 26 covered thereby. The high tension circuits through the tens and hundreds bank being open in the distributor, they will not tend to be completed by sparks julnping from the radial bar 28 through tens and hundreds perforations 26.

After the segment 115 of the distributor rides off the units brush it moves across a gap to the tens segment 117. During its movement across the gap, the contacts 105 are again closed by the cams 110 to build up the potential in the induction coil. At this time, there will be no tendency for a spark to jump through any of the perforations because of the gap in the distributor contacts. When the arm 115 engages the tens se ment 117, the spark will jump from radial ar 28 through the perforation 26 in front of the tens band 24, thus causing energization of the connected tens magnet l12.

Similarly: when the arm 115 engages the hundreds segment 118, a spark will be sent through the perforation 26 in front of the hundreds band 24 and a magnet 42 connect-ed to this band will be energized.

The engagement of the distributor brushes 116, 117 and 118 with the contact segment 115 is timed with the control of contacts 105 by teeth 110 of ratchet cam 109 in aecordanee with the scheme of Fig. 14 wherein the shaded sections of the figure indicate periods of closed contacts. This figure shows that contacts 105 are closed before engagement of a units, tens or hundreds brush with contact segment 115.

i,914,sss

The circuit through the primary `being thus closed, interrupter 102 functions to charge the secondary 111. YVhile contacts 105 are still closed, brush 116, 117 or 118 engages the contact segment 115 of the distributor to close a high tension circuit. The charge in secondary 111 now tends to discharge as above described. When brush 116, 117, or 118 and contact segment 115 are about midway of their relative travel, cam 105 releases blade 104 and contacts 105 ppen thereby breaking the primary circuit.

The break is abrupt and causes a rapid change in flux lilies of the primary, thereby inducing a peak charge on the secondary. A maximum voltage in thc high tension circuit is thus generated when the. brush 116, 117` or 118 is about midway of the contact segment 115. 1n this manner, it is assured that enough energy will be furnished when needed for closing the gaps in the high tension circuits. It is also evident from Fig. 14 that by the time brush 116, 117, or 11.5' disengages segment 115, the primary circuit has been broken long enough for the induced E. M. F. in the secondary to reach a minimunn'so that there will be no tendency for sparking to occur upon separation of a brush 116, 117` o1` lldfroni segment 115.

Figs. 7 to 14 illustrate the means for operating contact disk 109 and distributor 114.

Mounted on a base. 12() is an upright 121 of insulating material which supports a solenoid 122. The latter when energizedattracts its plunger 123 which at its lower end supports a rack 124 sliding in a guidel 125. Rack 124 meshes with pinion 126 which is free to turn on shaft-127. The upward movement of plunger 123 turns pinion 126 clockwise, as viewed in Fig. 11, for a single revolution. The pinion 126 is engaged with a projection 128 on a dog 129 pivoted to a disk 130 fast t0 shaft 127. The dog 129 is normally urged by spring 131 towards the pinion 126. lVhen the latter rotates clockwise. it carries dofr 129 along with it, thus rotating shaft 127 or one revolution. When spring 132 returns plunger 123 to itslowcr position, pinion 126 is rotated counterclockwise.

During this movement, the teeth of the pinion merelyv engage the right side of projection 128 of dog 129 to cam the dog ontwardly against resistance of spring 131 without imparting rotation to the dog or its carrying disk 130. Thus shaft 127 docs not rotate when the plunger returns to initial lower position.

This distributor is mounted on the lett A hand end of shaft 127 as viewed in Fig. 9. "i

The distributor comprises an insulator hub 133 (see Fig. 13) fast to the shaft. Encircling the hub 133 at the right is the contact ring 114 constantly engaged by brush 113. Extending axially from the ring 111 135 and upright 121 is provided to hold the l cup against rotation4 in of the upright.

Ratchet cam disk 109 is of insulating material and is pinned to shaft'127 adjacent the right hand end of the latter as viewed 1n Fig. 9. Contact blades 104 and 106 are sethe 'locating groove cured to the base 120 in cooperative relation.4

to the cam disk 109 as shown in Fig. 12.

As in the second modification, energization of magnets 42 causes magnets 49y and 50 to be energized to set the recording de@ vices. The making of any of the circuits is initiated by operation of control button 98 when the scale comes to equilibrium under i, an applied load asexplained with respect u y l- The recording mechanism to be to the second modification. v.;

described below and shown in Figs..15 to 20is adapted to be controlled by any ofthe three forms of scale sensing devices shown. inv Figs- 1 to The fecorderzincludes three banks of @1e-J ments, one bank for each denomination of al three denominationalorder number. The hundreds bank has only four magnets 50,

1 each associated lwith one of the hundreds bands 24, while the tens and units bank have each nine magnets 50, each associated with a.

corresponding tens or units band 24. A fourth iccorder bank is shown in Fig. 15

which is adapted to be controlled b a frac-p tional pound sensing device fully escribed in a copending application, Serial No. 506.650 and which is not concerned with the present invention.

Themagnets 50 of each bank are arranged arcuately about the main operating shaft 140, Each bank of magnets is carried between two side plates 141 (Figs. 15 and 18). To these plates are pivoted the, armature pawls 142 coacting with the magnets. Snitable springs (not shown) normally hold the associated pawls 142 retracted relative to the magnets. The noses 144' of the pawls are disposed opposite associated lugs 145 integral with and arcuately disposed on a member 146 of the bank.

The. member 146 has at one side a rack portion 147 meshed with a pinion 148 on a shaft 149. The shafts 149 operated by the members 146 of each recorder bank are in nested formation as shown in Figs. 15, 16, and 18. The pawl vnoses of a bank are differentially spaced from their associated lugs 145 in a manner to stop the member 146 after it has moved one to nine definite steps. Thus the first' uppermost awl is adapted to stop the member 146 a ter the 145. Thus if the magnet 50 connected to the units band 24 for reading 8 on the scale is energized, it attracts its pawl 142 to position it for stopping member 146 after it has moved eight steps.

The pawls after actuation are locked by detent plates 152- (Figs. 18 andy 19) there being one to each bank. Each plate has several elonffatedslots 153 pins 154 (Bi s. 18 and l20) of the pawls of a bank. djacent the nose end, a pawl lhas a thin fiat tongue 155 adapted to seat in either of the notches'156 or 157 of slots 158 of the detent plate. When a pawl is in retracted position, its tongue will be alined ywith notch 156 and when in actuated position, its tongue will' be alined with ynotch -157 vPrior to actuation of the detent plate, the tongues he in the upper and wide part of slot 158. a

When the detent plate. is actuated upwardly one of the notches 156 or 157 engages the pawl tongue 155 to hold the pawl against movement. The detent plates are operated by arms l159 pinned to their lower ends, these arms being Ifast to a shaft 160 (Figs. 17 and 18) operated from the control button 98.

4When the control button 98 is depressed, it rocks a bell lever 161 loose on shaft 160 clockwise against resistance of a spring 162. The-arm 163 of this lever is connected by a spring 164 (Fig. 17) to an arm 165 fast to shaft 160. Thus the shaft 160 is yieldingly rocked clockwise. vCarried by' shaft 160 is a cam 160 for engaging the lug 74 riding on pivot on upper blade 74 of contacts 73. When the detent plates 152 for locking the pawls.

Cam now rides off the contact lug 74 permitting contacts 73 to open and cause deenergization of magnets 50. While this is occurring the outer end of arm 165 formed as a blocking lug 166 rides off the right hand side of a number 1 67 (as viewed in F ig. 17). An integral project-ion 168 of the arm 165 is then caught under a projection 169 of a. pivoted latch 170 urged towards arm 165 by spring 171. member 167 is fast to the operating shaft normally l' The 140. The latter may now be moved counterclockwise by a crank handle 172.

Fixed to shaft.140 are bell levers 173 (Figs. 15 and 18) one'to each recorder bank. Connected by springs 174 to the levers 173 are levers 175 rotatably carried by shaft 140. These levers 175 are pinned to the previously mentioned rack members 146. Thus members 146 are yieldingly drawn along with shaft 140 upon operation thereof counterclockwise. The members 146 will move until lugs 145 thereon are engaged with and stopped by `the actuated pawls 142. In this manner, the members 146 and the shafts 149 operatedd thereby are stopped according to the load on the scale sensed by the selector mechanisms.'

After members 146 have been stopped, shaft 140 and levers 173 continue to move stretching springs 174. To compel movement of shaft 140 to the end of its stroke, a suitable full-stroke pawl 176 (Fig. 17) cooperates with ratchet teeth 177 on member 167. l

Each shaft 149 has fast therewith an indicating wheel 178 which may be seen through the sight window of casing 179.

The reading of the scale is permanently recorded by perforating mechanism which planches a tabulating card according to the ollerith system in which' each card column has ten positions 0 to 9, aperforation in one of these positions representing the-num'- ber corresponding 'to the position. The

posts 183. The frame mais diviaedfiam two sections 184 and 185 separated-.by anarrow groove for receiving a plate. Slidably guided for movementbetween fixed plate 181 and the vframe piece,v

187 above it are interposer bars 188, one for each column ofpunches. The bars 188 are provided with racks 189 in mesh withpinions 190 which actuate the-bars to position the lugs 191 thereof above one ofthe punches in each column. Y

Each pinion 190 is fast to one of the series of nested shafts 149. Thus when the rack members 146 are differentially positioned i under control of the pawls 142, the shafts 149 simultaneously operate both the register wheels 178 and the pinions 190. The latter move the interposers 188 so that the lugs 191 thereon cover the punches 180 corresponding to the act-ive pawls 142 and to the reading of the register wheels 178.

-'After the interposers have been differentially positioned, the card v- 186 is punched by the frame 182 moving upwardly carrying the card with it. Those punches not restrained against upward movement by the interposer lugs 191 will move with the card surface while those punches restrained by lugs 191 will penetrate the upwardly moving card. To move frame 182, a link 194 is connected to the lower die plate 185 and to a bell lever 195 having its upper end received in the cam slot 196 of a member 197 fast to the operating shaft 140. The cam slot 196 is shaped to oscillate the bell lever 195 after the shaft 140 has moved an amount equal to the full forward stroke of the members 146.

After the punching operation, the operator reverses the movement of crank handle 172 and-shaft 14() operated thereby. During this movement the blocking end 166 of the arm 165-rides off the co -entric portion 198 of member 167, (Fig. 1%. The spring 162 ynow .actuates bell lever 161 counterclockwise. r'The arm 163 of the lever has a stud 199 which engages with the lower edge of arm 165 causcs.tl1c latter to also rock counterclockwise. Shaft 160 rocks correspondingly and through arms 159 returns dctent plates 152 to lower position thereby unlocking pawls 142 which are returned to normal positions by suitable springs. During the same movement of shaft 160, the cam lug 160 rides over the lug 74 on upper lContact, blade 74.

, relation between bars 28 and strip 32 iasiich'that as ark from the `tri w'll 'um The upper sectlon 184 serves to guidelthe" p s p l l p lower portion of the punches while the ldwerf section 185 serves as the usual perforated-die.

bar.` Thus, if the load on the Yscale'fis 135.6'lbs.,-.,the spark will jump to the f bar 28 covering rforations 26 representing 2136 pounds.

he difference between the exact weight and the analysis of this weight istlthus only,0.4 of s; pound. If, accidentally the' ysparkfjumps to the bar 28 covering perforationsycorresponding to 135 unds, the errori` will be only 0.6 of a oun 'In any case, the error will less than a pound. Thiais` due to the fact that once a spark jumps ltoa' bar 28, the bars being insulated from eachother, the charge on this bar cannot escape to any other bar and through any perforations 26 except those covered by thef particular barvto which a spark has jumped from conductive strip 32.

In Fig. 21 is a modification of the load analyzing lmeans which while simpler is not as accurate since the chances 'for error are greater.

In this modification the pointer 14 is proi has been vdisclosed in connection with the f vided as in the other forms with ,a bracket 30, an insulating plate 31 attached thereto and a conductive strip 32. Departing from the other modification the conductive strip 32 has rigidly attached thereto a radially extending strip 21() of light conductive material. This radially extending strip is diiectly adjacent the perforated mica disk 25 and of substantially the same width as one of the radial conductive bars 28`of the other modifications, all ofvwliich bars it replaces.

In the operation of the scale the pointer 14 and the radial strip 210 will move together. The strip 210 will thereby be located in front of a set of perforations 26 in the mica disk 25 which corresponds to the reading on the dial 15 by the pointer 14. As in the` previous modifications the secondary of the induction coils is connected tothe conductive ring 29. lVhene'ver the circuit to the secondary is interrupted a spark will jump from the conductive ring 29 to the conductive strip The charge in strip 32 is conducted to radial strip 210 kfrom which sparks jump through perforations 26 behind the latter strip tothe bands 24 exposed by the perforations. The remaining mechanism is the same as has been described in connectionv with the preferred :form of analyzing de-l vice. j

It Will be evident in the second modification just described, that when the strip 210 is positioned equidistant between two sets of perforations such as for example correspond to 199 and 200, a spark may jump' from t-lie stripitoeither the or the`200 pound band 24, another spark may jump from the strip to the 9() pound band, and

a spark lmay jump to the 9 pound band.` Thus, it is possible that instead of the ana-V lyzer reading 199 or 290, the analyzer may read 299. This eri'or is not possible in -the first modification using radial bars, as the latter confine the analysis to a definite load. Thus if a spark jumps to the bar 28 covering the 199 pound perforations, there from this bar to the bar adjacent which covers the 200 pound perforations because the bars 28 are thoroughlyinsulated from each other.`
